How do I make a multiple coloured theme inside game

Okay, I want to make 2 colours theme. Black and white. User can switch between them but the problem is when the user choose black for example, and then they go to back(to another layout), the colour is back to the default colour, which is white. This is really bad... how to fix this??? I use persist but it's not helping me because the use of persist is not what I want. I also try to use the destroy and then create the background white object but not working too... please help???

I solved it!!! Just click on the object, at properties bar, select the Global to Yes! But now, it's not working anymore... wtf??? Okay, now it works but after I pressed the white theme icon twice. Or it will just be the default one, which is black... ugh... is this engine is really unstable???

It could be a bug, but it's more than likely a problem with your Events, but if we can't see what you've done then it's impossible to help you effectively.
